MV & VA-1000 Series
General Description
The 1000 series linear actuators are designed to be used
with Low thrust control valves, capable of accepting standard
analog current and voltage control signals. The brushless
stepper motor design provides smooth, highly accurate
positioning, with positive position-lock when not in motion.
The VA-1000 Series is ideally suited for valve, regulator
and metering pumps requiring exact position control and
unrestricted continuous modulation.
Features
• Permanently lubricated for any position mounting.
• Amplifier supplies current to hold last position and
prevent backdriving, up to thrust rating under power.
• AC or DC input power versions.
• 4 to 20 mA position, loop-powered, feedback signal.
•

SM-1000 Series
General Description
The SM-1000 Series are multi-turn, rotary actuators, designed
to meet the exacting requirements for closed-loop modulating
positioning control. Designed for low to medium torque rotary
applications, these actuators are capable of accepting analog
current and voltage command signals. The brushless stepper
motor design provides smooth, highly accurate positioning,
with positive position-lock when not in motion and powered.
The SM-1000 Series is ideally suited for regulators, pilot
valves, small quarter-turn valves, choke valves and dampers.
All SM-1000 Series actuators come with a standard digital
internal amplifier. These amplifiers are all fullfeatured devices
designed to work seamlessly with the actuator for closed
loop control.
Features
• Permanently lubricated for any position mounting.
• Amplifier supplies current to hold last position and prevent
backdriving, up to thrust rating under power.

Applications
Water Treatment Application
MV-1020
• Chemical feed valve control.
• Controls the ALUM that is added to raw, potable water.
• Through the DCS, flow rate is accurately controlled via a needle valve.
• Application environment is outdoors, which requires a
NEMA 4 enclosure rating. The application requires
unrestricted modulating duty.
• Remote Auto/Manual enclosure required that included power status relay.
Recycling Plant Chemical Injection
MV-1020
• Emissions control on digester gas combustion in
cogenerators.
• Controls levels of hydrogen sulphide in combustion gas.
• Flow is controlled by a 4 to 20 mA signal from the DCS.
• Explosion proof version of MV1020 modulates a 1”
Bauman valve to an accuracy of +/- 0.1%.
• Hydrogen sulphide controlled to 50 ppm.
